| - | With ignition key switch turned ON, engine not running, transmit data should typically create a voltage on the SDB line (LtGreen/Violet Wire) of 0.6-0.8 volts. The range of voltages that might be seen as acceptable during operation is 0v - 7.0 volts. | + | With ignition key switch turned ON, engine not running, transmit data should typically create a voltage on the SDB line (LtGreen/Violet Wire) of 0.6-0.8 volts.
